CAR-SEAT.

Specification of Letters Patent.

Patented Oct. 15, 1918.

Application filed March 2, 1915. Serial No. 11,511.

To all whom it may concern:

.. of the type in which the back can be shifted from one side of the seat to the other and in which the seat section is tilted to correspond to the position of the back.

A. furtherobject of the invention is to make the parts of the seat, particularly the moving parts, suitable for manufacturing out of pressed steel.

- A still further-object of the invention is to dispense withmachine work in preparing the parts for assembling.

Another object of the invention is to increase the strength and rigidity of the moving parts and to reduce the weight of the seat.

These objects and other advantageous ends I attain in the following manner, reference being had to the accompanying drawings, in which:

Figure 1 is a longitudinal sectional view of suflicient of a car seat to illustrate my invention, the seat, in the present instance, be

mg of the type which is provided at one end with a wall bracket and at the other end with a pedestal.

Fig. 21 is a sectional view showing one of the stops for the back section.

Referring to the drawings, 1, 1 are the two longitudinal angle bars which connect the end bearing plates '2 and 3. The seat structure, in the present instance, is supported at the wall side of the car 5, as shown by dotted lines in Fig. 1, by a bracket 4, which is secured to the side and extends under the seat structure and is fastened thereto by bolts 6 which also secure the bars to the end bearing plate. The bearing plate at the aisle end of the seat is secured to the bars by bolts 6*. I l

7 is the pedestal which is located under the car seat some distance from the aisle end thereof and is secured to the bars 1, 1, as shown in Figs. 1 and 2. Each bearing plate 2 and 3 has a lip 8 at each end thereof which extends back of the bars 1 and aid the bolts in holding the structure rigidly in position. 9 is the seat section and 10 is the back section. The seat section 9 rests upon rockers.

11, as shown clearly in Fig. 6, and pins 12 on these rockers extend into the openings on of the bars 1 and have flanges 13 which are cut away at 14. Plates 15 and 16 aresecured to the ends of the structure and have tongues which extend over the flanges 13 of the rockers so that the rockers are prevented from,

lifting by these tongues, as clearly shown in Fig. 4.

Secured to the back section 10 are the arms 19, preferably made of pressed sheet steel in the form illustrated in Fig. 7, and bearings 20, 21 and 22 are pressed from this sheet, as illustrated in the drawings, so as to force the raw edge of the metal away from the bearing point, thus dispensing with machining. A cap plate 23 is secured to each arm 19, as illustrated in Fig. 7. This cap plate not only covers the opening 20, but also acts as a reinforcement for the arm at the joint or weak point. The cap plate has side extensions 25 which inclose the gap at the pivot rod 24, as the back of theseatstructure is less in width than the seat cushion.

' 'Each plate 2 and 3 has three bearings 26, 27 and 28. These bearings are pressed as are the bearings 20, 21 and 22, and are for the same purpose. There is a seat back lever 29, Fig. 10, at each side of the seat structure and this has an extended bearing 30 formed by shaping the metal'by pressing.

This bearing 30 journals in the bearing 20 of the back frame 19. Within this bearing is a bushing 31 in which the pivot rod 24 is mounted and this bushing extends into the opening in the bearing 20 of the back frame 19 and the seat back lever is pinned to the pivot rod. This one side of the back to the other so that any motion given to the mechanism on one side of the seat will be transmitted to the mechanism on the other side without straining the back of the seat. The lower portion ofthe seat back lever 29 is pressed into shape,

asshown in the drawings, to form a bearing 32 which fits over the bearing 26, as illustrated in Fig. 14, and a rivet 33 having a wide head fastens the two parts together, as clearly illustrated in said figure.

' 34, 34 are the seat back links, two on each side, which have'bearings 35 and 36 fitting respectively the bearings 21, 27, and 22, 28

of the back frame 19 and the bearing plates 2 and 3. The parts are shaped as illustrated in Fig. 14, and are also connected by rivets.

These two links are slightly out of parallel with each other so as to guide the back sec tion and hold it in the proper inclined position. On each seat back lever 29 is an ex-' tension 37 having a pin 38 which enters a slot 39 in each'rocker 11 so that, when the 7 moved correspondingly inorder to give the seat section the proper tilt with respect to the back. I I

pivot rod 24 extends from In the present instance, I provide an end plate- 40 which covers the mechanism including the links and lever and this end plateis made hollow and in two sections. The inner section 41is flanged and the outer section 42 is also flanged. The flange of the outer sec- .tion extends over the flange of the inner section and is notched at 43 to receive the edge of the flange of the inner section, so that the two parts are'held rigidly in position when the flange of the outer section is beaded over the flange of the inner section, as clearly shown in' Figs. 4 and 9. The inner section 41 is recessed at 44 and in the base of each recess is a slot 45, the slot being wider at the upper end than at the lower end. The

bracket plate 15 has an upright portion 46 and a tongue 47 is bent from this upright -portion and extendsinto the wide portion turning.

;This particular seat is of the wall type and rests on a braeket,.as described above,

but it will be understood that if the seat be clear of the wall, then a pedestal, and, preferably, an end plate, may be secured wall end'of the seat structure.

It will be noticed that the lower end of eachseat back frame 19 has two notches 49, Fig. 7, and the portions 50 of thebracket to the .for the head of the bolt and keeps it from" plates 15 enter the notches, Figs. '2 and 21,- V

and act as a stop for the back section when it is shifted to either of its two extreme positions. v

In securing the several pivoted sections together, I use a rivet with'a large head, as illustratedin the drawings, and-the body portion of this rivet is pressed outas clearly shown inFig. 14, firmly holding the parts together, but it will be understood that a bolt, or other fastening device, may be substituted for the rivet.

It will be'seenfrom the above description that I am enabled to make all of'the-metallic portions of the seat from pressed steelor equivalent metal. The parts .arelight and no machining is required afterthe elements of the structure leave the press." The bearings are substantial and one bearing snugly fits another. The parts can be attached by rivets, since the strain'is taken. by the ribs or flanges around the bearings instead of by the-rivets themselves. As the parts are made from pressed sheet steel they are interchangeable and repairs canieasily be made without the aid of a skilled mechanic.

of longitudinal bars; end bearing plates secured to the ends of said bars and forming, with the latter, a supporting structure, each of said plates having three bearing portions formed thereon, the center bearing portion being above the other two portions; a back section; seat back frames secured to the back section at each end thereof, each of said frames having three bearings thereon, the

center bearing being above the other two bearings; a seat back lever at each end of the structure and mounted upon the center bearings of the end bearing plates and the seat back frames; a movable seat engaged by said back lever; and a pair of seat back links at each end of the seat structure and mounted 5 7 upon the outside bearings of the end bearing plates and the seat back frames and ofiset laterally in respect to the plane of movement of the seat back levers.

In testimony whereof I have signed my 20 name to this specification in the presence of two subscribing Witnesses.
